Abstract
Den foreliggende oppfinnelse vedrører en fremgangsmåte for fremstilling av alkylhalosilaner ved reaksjonen mellom elementært silisium og et alkylhalid ved forhøyet temperatur i nærvær av en kobberbasert katalysator og eventuelle promoterer. Aluminium i form av metallisk aluminium eller en aluminiumlcgcring eller en aluminiuminncholdcnde silisiumlcgering eller en aluminiuminncholdcndc forbindelse eller blandinger av disse, tilsettes til reaktoren i en mengde mellom 0,01 og l vekt % beregnet som aluminium basen på vekten av silisium som tilsettes til reaktoren.The present invention relates to a process for the preparation of alkyl halosilanes in the reaction between elemental silicon and an alkyl halide at elevated temperature in the presence of a copper-based catalyst and any promoters. Aluminum in the form of metallic aluminum or an aluminum alloy or an aluminum-enriched silicon alloy or an aluminum-enameled compound or mixtures thereof, is added to the reactor in an amount between 0.01 and 1% by weight calculated as the aluminum base on the weight of silicon added to the reactor.
